俄罗斯30m分辨率数字高程模型（DEM）数据

本数据集来源于最新发布的ASTER GDEM V3 分幅数据，经过粗差修正、空值填充和水域数值异常剔除等预处理，并采取图像拼接、投影转化、裁剪等步骤，生成了优化的30m分辨率数字高程模型（DEM）。

This dataset is derived from the newly released tiled ASTER GDEM V3 data. Preprocessing operations including gross error correction, null value filling and removal of abnormal water area values have been conducted, followed by further steps such as image mosaicking, projection transformation and clipping, ultimately generating an optimized 30-meter resolution Digital Elevation Model (DEM).
